Without checking first, Progressive shipped me a 306 when I ordered a 106. It's a better unit (1000w) but more bulky which is a small demerit for me as I travel a lot with my gear. But I'm happy enough to keep the meatier unit.

I bought this charger about 2 months ago and have subjected it to alot of use and its still holding up well way better then cheap chargers and not too much more (compared to thunder power) these guys here are great will definately be ordering from here again.

I've been making do with cheap chargers for several years, meaning to order an iCharger, but not wanting to spend the money. One day I realized that about 8 years ago, I paid $130 for a Triton, which did almost nothing, even compared to the cheapies I've been using. The next day, I made my order. It's been all I expected.

I have to say this charger is so easy to use, the menu is very intuitive and feature packed. Love the cell IR feature because it lets me know when a cell is going bad. I could go on and on but I am thrilled to have my 106b. It balance charges my 6s/4000mah (3s x 2, parallel board) in 22 mins.! Thanks ProgressiveRC for an amazing product that enhances my hobby experience. I use the 106b with a HP600pb/575w server power supply that I modified. Nice compact package that is exactly what charger I needed.
